MAGAZINE-CAMERA.

SPECIFICATION forming part of Letters Patent N 0. 643,7 56, dated February 20, 1900.

Application filed September 1l 1899. Serial No. 729,172. (No model.)

To @ZZ 107mm t may concern:

Be it known that I, LAIRD H. WALLACE, a citizen of the United States, and a resident of the city of Denver, county of Arapahoe, State of Colorado, have invented a new and Improved Magazine-Camera, of which the following is a specification, reference being had to the accompanying drawings, in Which- Figure l illustrates a plan view of the inro vention, the top of the camera or box being removed. Fig. 2 illustrates a vertical longitudinal section of the camera, taken through about its medial line, certain parts being shown in elevation and certain unimportant I5 parts omitted. Fig. 3 illustrates a perspective View of the magazine and certain of its coacting parts. Fig. 4 illustrates a perspective view of the exposure-chamber. Fig. 5 illustrates in elevation a detail of the magazine, the exposure-chamber, andthe quadrant whereby they are operated. Fig. 6 illustrates an elevation of the parts shown in Fig. 5, but in a different position. Fig. 7 illustrates a perspective view of a modified forni of frame or support for the magazine and certain of the coacting parts. Fig. 8 illustrates an elevation of the magazine, the exposure-chamber, and certain of the coacting parts in a slightly-modified construction. Fig. 9 is an elevation of the part shown in Fig. 8, but in a diiferent position. Fig. l0 is a perspective view of the exterior of the camera, showing the lever and indicator whereby the devices on the interior of the camera are operated.

A is the camera-box.

B is the lens,which is provided with a suitable shutter.

C is a handle whereby the apparatus as a whole may be carried.

D is the magazine. It is provided with spring-latches E E E2 E3, which are attached to its sides and project over one of the edges of the magazine, at what I call its discharging side or edge. The function of these latches is to retain the plate-holders within the magazine until released and transferred. The magazine also has other spring-latches F F F2 F3, which are presented at the opposite side or edge of the magazine, and their function is to take the plate-holders after exposure from the exposure-chamber and transfer them to the rear side of the magazine in a mann er which will be hereinafter explained. G G G G are corner-blocks at the several corners of the magazine, against which the compressor-plates H (see Fig. 2) rest when there are no plate-holders in the magazine, so that they will not drop away from it. The corners of the plate-holders themselves are beveled off slightly, so that they do not con-y tact with these corner-blocks. Y I I are springs which press the compressors apart and against the back sides of the plateholders. J J are pins setin one end of the magazine. The magazine is supported upon lateral arms K, which are connected to a suitable part of the camera-as, for instance, to the back plate or end of the camera-box (marked A in Fig. 2) or in any other way, as preferred. An alternative construction is shown in Fig. 7, which will be hereinafter explained, and upon the ends of these arms, respectively, are pins L, which enter journals in the ends of the magazine. M M are two spring-latches connected with these arms K, which are engaged by the pins J to control the position of the magazine in a manner hereinafter to be explained.

N N are iinger-like projections beyond the edges of the magazine front and rear, which serve as guides for it in the manner hereinafter to be explained.

O is a cross-shaft journaled in any suitable way upon the bottom or in the sides of the camera. One end of it projects through the side of the camera and is provided with a lever P, (see Fig. l0), whereby it is actuated, and within the camera and near the ends of the shaft O there are two quadrants keyed to it, (marked Q,) at one side of which are upwardly-projecting studs R, provided with pins S. In the quadrants are two slots T T', and near the end of one of the quadrants is a click U, actuated byspring V and provided with a hook W, which engages with a pin Y, which limits its movement. It is so arranged that when the quadrant is moved in the direction of the arrow (shown in Fig. 3) the click U engaging with the pins J J, respectively, will be depressed by such contact, but as soon as it has passed the pins it will IOO be elevated again by the spring V, so as to engage with the pins upon the backward movement of the quadrant.

The plate-holders are shown at Z Z, (see Fig. 2,) most of them being shown at the receiving side of the magazine, which in this iigure happens to be presented forwardly,but two of them, Z r are shown at the delivery end of the magazine.

The exposure-chamber is shown in Fig. 4. lt is composed of a box orframe a, having an opening b in its front, and is open entirely at the rear. c c are two spring-latches attached at the sides of the chamber, adapted to engage with the edges of the plate-holders by entering recesses CZ cl in the magazine when it and the exposure-chamber are brought up close together, as will be hereinafter explained. The exposure-chamber is also provided with recesses e e, adapted to receive the beveled ends of the spring-latches E, E', E2, and E3, and there is a plate or surface ffff at each of these openings which engages with theinclined ends of the latches,whereby they are lifted for the release of the plate-holders, and by the side of each of these recesses there is another recess g, within which, at the top and bottom, the guide-fingers N of the magazine enter, so that the parts are properly adjusted relative to each other, their edges being guided in such manner as to effect the proper transferof the plates. On the vertical edges of the exposurechamber there are other recesses 7L 7L h h and by the side of them smaller recesses i i, which receive, respectively, the side spring-latches F F F2 F3 of the magazine and the side guide-fingers N thereof. At each side of the exposure-chainber7 running vertically, there is a metallic platej, having in it a slot 7c, within which the pins S of the quadrants work, so that as the quadrants make their quarter-revolutions they alternately project and retract the eX- posure-chamber.

l l (see Fig. l) are latches whereby the rear of the camera-box is held in place. m is another one at the bottom of the camera, the latter being provided with a push-button it. (See Fig. 2.)

ois asmaller latch provided with push-buttons p at the upper side of the camera.

The operation is as follows: The parts are assembled as shown in Figs. 1 and 2, being in the first placein the position shown in Fig. .f2-that is to say, the exposure-chamber is in the forward part of the camera in its position adapted to take pictures, and the magazine is presented with its receiving side toward the exposure -cliamber, and the lever upon the outside of the camera is in a horizontal position. The lever is now swung upwardly until a projectionp upon its end engages with the last notch (marked 0) on the indicator q. (See Fig. l0.) I prefer to make the lever P slightly spring-acting or elastic, so that the terminal finger p thereon shall snap into the notches in the gage positively, so that the indication may be sure. Equivalent devices may be used for those just taken. As the quadrant tips over backwardly, due to the stated movement of the lever, the pins s, engaging with the slot 7.: at the side of the exposure-chamber a, move the exposure-chamber backwardly toward the magazine, and as the quadrant moves the click U (which I usually have on one of the quadrants) engages with one of the pins J on the magazine and rotates it over forwardly toward the approaching exposure-chamber, and the pin J, with which the click engages during the movement of the quadrant, can enter the slot t therein, as may be desired7 and as the next pin in turn moves downwardly it can enterthe slot t in the quadrant. As the magazine goes over one of the pins J comes in contact with the inclined or arc-like surface of the springlatch M, which, as before stated, is attached to one or both of the arms K, upon which the magazine is supported, and presses this spring latch or latches, as the case may be, outwardly until the pin reaches its uppersurtace, whereupon the latch rebounds beneath the pin, so that backward turning of the maga' zine is prevented. The lever P is moved np wardly, as before stated, until the iingerp on its end engages with the last notch of the indicator. When it has reached this position, the adjacent edges of the magazine and the exposure-chamber are brought snugly in contact with each other and the guiding-fingers N N upon the magazine have entered the recesses t t' and g g, provided fer them on the rear edge of the exposure-chamber, in such manner that these two receptacles are accnrately registered with each other and brought into the desired relative positions. It will be observed that owing to the fact that the inagazine has made a half-revolution by reason of the action of the quadrant upon it, as just described, the delivery side ot' the magazine is now in contact with the exposure-chamber, and that owing to the close contact secured, as above stated, between these vparts the retainingsprings E, E', E2, and E3, which normally hold the plate-holders within the magazine, have been moved by coming in contact with the plate ffff upon the exposure-chamber, so that the plates are freed within the chamber, and also that the spring-latches c c at each side of the exposure-chamber have by their impingement against the edges of the foremost plate-holder been lifted and allowed to catch in behind those edges, since they have unobstructed movement within the notches e e, provided in the front edge of the magazine for this purpose,so that these springlatches c c will upon the separation of the magazine and the exposure-chamber retain within the exposure-chamber and in proper focal position the said outside plate-holder. To obtain proper focus, the lever P is now moved along the indicator to the proper distance, as shown thereon by figure or other indicia, and it will be observed that during the IOO IIC

forward movement of the exposure-chamber the magazine remains at rest, being held against rotation by one of the pins J, resting upon the upper side of the spring-latch M, there being no movement of the magazine until the reverse or rearward movement of the exposure-chamber takes place. Then it has been properly focused, the exposure is made in the usual way, and thereupon to remove the exposed plate to the rear side of the magazine and substitute a fresh unexposed plate the lever is pressed farther forwardly to the end of its movement, so as to carry to completion the forward movement of the quadrant and bring the click in front of the pin J on the magazine with which it is to coact. Upon reaching the extreme forward movement of the quadrant the lever is again brought rearward to a vertical position until the catch p upon its extremity engages with the last notch (marked o) of the indicator, thesame as before. In so doing the click U a second time engages with another one of the pins J and the magazine is rotated a half-turn, the same as before, with the effect of now presenting the receiving side of the magazine to the exposure-chamber. The contact between the two is made positive and certain in the same manner as above explained, with the differences, however, that when this-z'. e., the receiving side of the magazineis brought in contact with the rear of the exposure-chamloer the springs o c, which hold the exposed plate within the exposure-chamber, are lifted by coming in contact with the edges of the magazine on which there are no notches d d, which were presented at the other side thereof, so that the retaining-latches c c are lifted, and the plate in the exposure-chamber is now free to move, and simultaneously with the above operation the spring-latches F F F2 F2, which have free movement within the recesses 7i 7i 7i 7L in the edge of the exposurechamber, are lifted by the edges of the plateholder and catch over its forward surface, so that when the magazine and exposure-chamber again separate the plate will have been v received within the rear side of the magazine and will be retained there and removed from the exposure-chamber by these latches F F F2 F2. Now to again deposit an unexposed plate within the exposure-chamber the operation of the parts first described is repeated. In this manner the plates are in succession transferred from the delivery side of the magazine into the exposure-chamber, there exposed, and then transferred back again into the receiving side of the magazine, and this is continued until all of the plates are exposed.

Although I have shown four spring-latchesi. c., E E E2 ES-acting on the delivery side of the magazine and four other spring-latches F F F2 F3 acting upon the receiving side thereof, obviously a less number may be employed in both cases. Also it may not be necessary under all circumstances to have the guiding or centering ungers N N, dsc., with coactin g notches in the exposure-chamber, and in Figs. 7, 8, and 9 I show a modified construction of certain of the parts, which in some respects I prefer to those illustrated in the other iigures. They are as follows: Instead of employing the arms K, supported at the sides of the camera, above the bottom, and the spring-latches M upon them and having the shaft o journaled separately upon some suitable part of the camera-box it is advantageous under certain circumstances to employ the devices shown in Figs. 7, 8, and 9- that is to say, as a support for the magazine and coacting parts I make a frame of metal d', which may be attached by screws or otherwise to the bottom of the camera, and the trunnions L, upon which the magazine rotates, I set in the inner faces of the two uprights of this frame, and att b I make two journals within which the shaft O will operate, and in a projection c from the frame a I attach a spring d', having a hole e near its end, and projecting from the two edges of the magazine D, I provide two short pins f', which are adapted to enter the hole e' in the spring d',

and upon the shaft o, taking the place of one of the segments, I arrange a mere bar or crank-arm g', carrying the piu S, the same as before, and provided with a projection h', which is adapted to engage with the spring and depress it when it is desired to release the magazine for its rotation. This construction of the parts has the following advantages: First, inasmuch as the trunnions which support the magazine and the journals for the cross-shaft O are all within the same piece of metal their proper alinement and relationship to each other are permanently maintained; also, owing to the fact that the pinsf engage with the spring, depressing it and entering the hole e' therein at each half-revolution of the magazine, the latter is by this engagement prevented from rotating in either direction, whereas in the construction heretofore described and as illustrated, for instance, in Fig. 3 the latches M on the arms Y K hold the magazines against rearward rotation only. This is all that will be necessary in the majority of cases; but circumstances might arise in which it(would be desirable to have the magazine held positively against rotation in either direction.

I do not limit myself to the details shown and described, since obviously they may be considerably departed from and yet the essentials of my invention be employed.

Having described my invention, I claiml. In a camera the combination of an exposure-chamber, a rotating magazine, means to move the said parts into contact with each other, means to rotate the magazine, means to transfer a plate from one side of the magazine into the exposure-chamber and other means to transfer a plate from the exposurechamber into the reverse side ofthe magazine, for the purposes set forth.
